Join Kevin Skoglund for an in-depth discussion in this video Create minute selector, part of Easy PHP Projects: Time Zone Conversion.
- [Voiceover] In this previous movie we created…a generic function that proved to be really useful…when creating options for our date selections.…Over the course of the next two movies…we're going to build on that work…and create select options for the time selectors…starting with the minute options.…We'll come back to the hours in a moment.…First we're going to start with the minutes.…That's because it's a little bit simpler…to work with the minutes.…Minutes is just going to be a range of numbers…from 0 up to 59.…The only catch, the only thing that makes…this difficult, is that the values for the numbers…are going to be the numbers 0 to 59…but the labels that we want on them…that the user is going to see…need to be 0 padded on the left side.…
That is 00, instead of just 0, 01 instead of just 1.…So if the number is less than 10…we're going to need to put a 0 on the left side.…Now you could just write some basic PHP code…that would loop through all of these numbers…covert each one of them into a string…and if the number was less than 10…
